This is my first time contest submissions and I wanted to know some stuff from experienced people.

What's the most common format that everyone one sends in? I know that some take mpeg-1, mpeg-2 , etc . But does that mean that they take in teh mpeg-2 format SVCD or DVD? Or is it even possible to format someting to DVD mpeg-2 standards and burn it on a cdr if it fits?
